• Create data pipelines for structured & unstructured data (web scraping, PDFs, Excel).
• Implement OCR, vector search (Pinecone), and RAG systems.
• Automate workflows using n8n & Python.

• Expert in Python and AI integrations.
• Skilled in web scraping, OCR, embeddings, vector DBs.
• Experience with custom model training & agent orchestration.

If you love building AI-driven products, designing intelligent workflows, and working with cutting-edge tech, we want to talk to you!

• AI & LLM Development: Build agentic workflows using LangChain, OpenAI, Gemini, and custom orchestration; design context-aware RAG systems for accurate retrieval and response; fine-tune models for domain-specific tasks using LoRA, PEFT, RLHF.
• Data Processing & Extraction: Build robust web scrapers for structured and unstructured sources; implement OCR solutions for PDFs, images, and scanned documents; parse Excel sheets, PDFs, and semi-structured data, extracting and matching entities across datasets; normalize and structure raw scraped and document data for downstream AI workflows.
• Vectorization & Retrieval Systems: Implement and optimize data vectorization pipelines for semantic search; use Pinecone, FAISS, or Weaviate for vector storage and similarity search; apply dimension reduction techniques (PCA, UMAP) for efficiency.
• Workflow Orchestration & Automation: Use n8n and similar tools for rapid prototyping and automation; build modular pipelines for continuous data ingestion and transformation.
• Infrastructure & Integrations: Develop APIs and connectors to integrate AI-driven insights with Bolsterup’s core platform; deploy solutions using Docker, serverless architectures, and cloud platforms (GCP / AWS); implement monitoring for AI pipelines, including token usage and latency tracking.
